Hi Hillary! Welcome to planDisney!
You are super close to your vacation now! Yay! I love hearing from Guests that want to upgrade their fun-filled days because it always feels great to add to the magic!
For a multi-day
Walt Disney World theme park ticket, you can't upgrade just one of your days. You will need to upgrade all days to the Park Hopper Option. The upgrade may be worth it if you want to hop to a different theme park each day! You can price out the upgrade on the
My Disney Experience mobile app. Just touch the three lines in the bottom right-hand corner of the app, then "Tickets and Passes." You should see your current ticket on the next screen (if not, you can link your ticket there first), plus the option to "Change Ticket" below it. Choosing that will walk you through the process to upgrade. Even if you decide to cancel the process and not upgrade yet, you can at least get an idea of the total cost.
I hope this helps, Hillary! Please let us know if you have any other questions.
Tabitha
